Converting station tubular busbar on-line monitoring system

Abstract

The invention discloses a converting station tubular busbar on-line monitoring system. A sensor chamber is fixedly installed at one end of a tubular busbar. A passive sensor head is fixed inside the sensor chamber and connected with a master control central processing unit (CPU) in an electric mode through optical cable. A semi-conductor crystal is fixed on the tubular busbar. Two optical fibers are distributed on two sides of the semi-conductor crystal in a bijective mode. A solar cell panel and a storage cell are respectively connected with a power supply module in an electric mode. The power supply module, a photoelectric detector, a video camera and the master control CPU are respectively connected with a data transmission module in an electric mode through an operating condition acquisition module. A data receiving module and a data processing module are respectively connected with a data storage module and a displayer in an electric mode. The converting station tubular busbar on-line monitoring system has the advantages that displacement and temperature of the tubular busbar and integrity of a brace china bottle can be monitored in an on-line mode, monitoring accuracy can be effectively ensured, and real-time monitoring of the integral system for 24 hours can be achieved.

Description

technical field [0001] The invention relates to the technical field of on-line monitoring systems, more specifically to the technical field of on-line monitoring of tubular busbars of substations. Background technique [0002] The essence of tubular busbar is to use copper tube or aluminum alloy tube as a conductor, and a busbar product with external insulation. Tubular busbar has the characteristics of large current, high mechanical strength, good insulation, and wide application range, so it is being used by more and more people. recognized and accepted by customers. However, in actual operation, due to the influence of high-frequency vibration and wind force on the tubular busbar, temperature changes, system operation mode, faults in the vicinity of the busbar, faults in the busbar fittings, etc., the displacement between the tubular busbar joints of the EHV line will be reduced. Gradually increasing or even falling off will bring catastrophic accidents. Therefore, the u...

Problems solved by technology

However, in actual operation, due to the influence of high-frequency vibration and wind force on the tubular busbar, temperature changes, system operation mode, faults in the vicinity of the busbar, faults in the busbar fittings, etc., the displacement between the tubular busbar joints of the EHV line will be reduced. Gradually increasing or even falling off will bring catastrophic accidents. Therefore, the ultra-high pressure tubular busbar joints are absolutely not allowed to fall off, and sometimes the failure of the busbar support porcelain bottle will break, which will affect the safe and reliable operation of the substation and easily cause substation failure. Full shutdown accidents are a great hidden danger. In order to prevent problems before they happen, at present, there are only mechanical displacement and sliding measurement devices for tubular busbar monitoring in China. There is no near-area image monitoring, no special temperature measurement devices, and mechanical displacement and sliding measurement. The device has no data output equipment, the accuracy of the measured data cannot be guaranteed, and 24-hour real-time monitoring cannot be realized
